Value Collection R63288249 Brass Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION R63288249 is a brass thumb screw with an oval head profile and a 5/16-18 UNC thread specification. Designed for hand-tightening applications where tools are impractical or unnecessary, this fastener provides a secure hold without requiring a driver or wrench. The oval head measures 0.7 inches in diameter and 0.78 inches in height, giving it a low-profile dome shape that seats cleanly against panels, covers, and access doors. Overall length is 2 inches. Machined from brass, it offers natural corrosion resistance and is well suited for environments where ferrous fasteners would be undesirable. Trade professionals and maintenance technicians use this type of fastener across HVAC access panels, electrical enclosures, plumbing service covers, and similar assemblies.

This thumb screw is appropriate for light industrial, commercial, and residential service applications where frequent hand access is required. The 5/16-18 UNC thread is a common coarse-thread standard found on a wide range of enclosures, panel frames, and equipment housings. Its brass construction makes it a practical choice for installations where galvanic compatibility with aluminum or other non-ferrous materials is a concern. Supplied individually, it is a straightforward one-for-one replacement or new-installation fastener.

Compatibility

Designed as a standard 5/16-18 UNC thumb screw replacement or new-installation fastener for enclosures, access panels, and equipment covers requiring hand-removable brass fasteners.

Installation Notes

Installation requires no tools under normal service conditions due to the oval thumb head. Ensure the mating thread in the panel or nut insert is clean and free of debris before threading to avoid cross-threading the brass fastener, which is softer than steel. Power down or de-energize any enclosure before removing or installing access panel fasteners per applicable NEC or equipment manufacturer guidelines. Do not use an impact driver or apply excessive torque, as brass threads can strip or gall under overload.
